Here are some examples of how to use the functions provided in this package:

Finance Module (finance.py)

This module provides a function to calculate compound interest.

interest(prime_amount, time_duration_str, number_of_times_interest_will_compound_per_year, rate_of_interest)

Calculates the compound interest.

• prime_amount (float or int): The initial principal amount (P).

• time_duration_str (str): The duration for which the interest is calculated, must be in specific short-hand formats:

  • "XyYm" (e.g., "5y6m", "1y8m" for 1 year 8 months)

  • "Xm" (e.g., "15m", "6m" for 15 months, 6 months)

  • "Xy" (e.g., "5y", "1y" for 5 years, 1 year) Where X and Y are whole numbers.

• number_of_times_interest_will_compound_per_year (float or int): The number of times interest is compounded per year (n) (e.g., 2 for half-yearly, 4 for quarterly, 12 for monthly, 365 for daily).
